Multi-Camera Adapter Board


This adapter bard supports 5MP and 8MP since the old multi-camera adapter board doesn’t work with Raspberry Pi 8MP IMX219 pi camera due to the camera driver issue. Now Arducam team designed upgrade the multi-camera adapter board for both 5MP and 8MP pi cameras. Consider that the high speed CSI camera MIPI signal integrity is sensitive to long cable connection, the new adapter board can only connect maximum 4 cameras to a single pi board. Because it covers the most of the use cases like 360 degree view photography and surveillance, and add more cameras will degrade the performance of the cameras. Like always please note that Raspberry Pi multi camera adapter board is nascent product that may have some stability issues and limitations because of the cable’s signal integrity and RPi’s closed source video core libraries, so use it on your own risk.

The latest revision of the Arducam Multi Camera Adapter is V2.2. The V2.2 undergoes firmware updates, but the specs, documentations, and tutorials on the V2.1 will still apply to the V2.2.


The V2.1 multi-camera adapter board is updated to support the Raspberry Pi Camera Module V2.1, namely the 8MP IMX219 cameras. However, no mixing of 5MP and 8MP cameras are allowed.
